metal-soy-critic

A utility for validating your metal-soy components. This tool is not meant to do the same work that your javascript or soy compiler already does. Instead it checks for anti-patterns in your components.

Usage

First install mcritic from npm:

$ npm install -g metal-soy-critic

Then pass it a directory containing soy files that you would like to check:

$ mcritic src

You can also ignore files matching a particular glob:

$ mcritic . --ignore "**/{node_modules,classes,build}/**"

Configuration

By default, mcritic will recursively search the current and parent folders for a .soycriticrc.json file from the current working directory. Here is an example:

{
  "callToImport": [
    {
      "regex": "(\\S+)",
      "replace": "{$1|param}"
    }
  ]
}

Here are the currently supported settings:

callToImport

This property is used to provide a list of replacement configurations. Each list item must contain two properties:

• regex

  This property is used to provide matches for replace. This should be a standard javascript regex that contains capture groups to be referenced in replace.

• replace

  This property uses match groups defined in regex to translate a component name in a soy template to its corresponding import name when validating their import.

  When referencing match groups from regex, interpolation should be in the form of {$n}, where n is the match group number. An example would be "{$1}.js".

  Interpolations can also contain named string transformations delimited by a |. This transformation corresponds to the functions provided by change-case.

  Examples:

  • "{$1|lower|snake}.js"
  • "{$2}-{$1}"
  • "{$1|dot}.js"

Type	Default
array	"[{"regex": "(.*)", "replace": "{$1}"}]"

implicitParams

This property is used to provide implicit params when checking if a Soy param is present in a component's STATE configuration. Here is an example:

{
  "implicitParams": {
    ".*Clay": ["visible", "elementClasses"],
    "DropDown": "open"
  }
}

Each key shoud be a valid RegExp string, which will be used to match a class name in your project. When a match is found, the value (which should be a string or Array<string>) will be added to the available params for that class when compared against it's Soy file.

Type	Default
object	{}
